Do you have net-snmp installed on your system ?

I did two things and problem is disappears for now (I live without changing
default route longer then ever now)

1. I disabled snmpd
2. I installed and started to use "bird" routing daemon.
With configuration like this.

protocol kernel world {


    persist;        # Don't remove routes on bird shutdown


    scan time 20;       # Scan kernel routing table every 20 seconds


    import none;        # Default is import all


    export filter {


        if (net =3D 0.0.0.0/0) then {


            if proto =3D "def" then accept;


        }


        reject;


    };



}



protocol device { }




protocol static def {



    preference 1000;    # Default preference of routes


    route 0.0.0.0/0 via x.x.x.x; # My default gateway


}

I don`t know is it helps or not at all, but you should try if you
in desperate situation as you told.
